n.[生]超显性
The classical hypotheses-dominance hypothesis and overdominance hypothesis were reviewed and evaluated in this article. 笔者综述了杂种优势遗传基础的两个经典假说-显性假说和超显性假说的基本观点、不足之处。
In Population H21 Mol7, nine QTL were detected for resistance to ACB, which were localized on chromosome 1,4,5,8 and 10. These QTL showed predominantly overdominance, subsequently dominance or partial dominance gene action. 对H21×Mo17群体，共检测到9个抗性QTL，分别位于染色体1、4、5、8、10上，表现的基因效应以超显性为主，此外还有显性效应和部分显性。
The inheritance of plant was characterized as overdominance; 株高的遗传为超显性遗传。
